They are particularly suitable for implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.
The ten latches of the BCT29841 are transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.
A SN74BCT29841 buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high or low level) or a high-impedance state
In the high-impedance state, the outputs neithe load nor drive the bus lines significantly. The high-impedance state and increased drive provide
the capability to drive bus lines without need fo interface or pullup components.
The SN74BCT29841 output enable (OE) does not affect the internal operation of the latches. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
The SN54BCT29841 is characterized for operation over the full military temperature range of 55°C to 125°C.The SN74BCT29841 is characterized for operation from 0°C to 70°C.
